Abstract
A wireless power transmission device includes a laser light source configured to generate a first laser light for wireless charging and a guide beam for sensing at least one of an object and one or more receivers; a light outputting unit configured to output the first laser light and the guide beam; a light receiving unit configured to receive the guide beam; and a controller configured to control output of the first laser light through the guide beam received at the light receiving unit.
Claims20
A wireless power transmission device comprising:
- a laser light source configured to generate a first laser light for wireless charging and a guide beam for sensing at least one of an object and one or more receivers;
- a light outputting unit configured to output the first laser light and the guide beam;
- a light receiving unit configured to receive the guide beam;
- and
- a controller configured to control output of the first laser light through the guide beam received at the light receiving unit.
A method of controlling a wireless power transmission device, the method comprising:
- controlling a light outputting unit to emit a guide beam to a target region;
- controlling a sensing unit to sense a light reflected from a receiver in the target region;
- determining the position of the receiver based on the reflected light;
- and
- controlling the light outputting unit to emit a first laser light to the determined position of the receiver.
